i love this theory! it makes complete sense, from what we know so far, and would fill in all the holes. ever since you guys mentioned the Miller’s daughter might be Regina i’ve been trying to figure out how it could be, cause it just seems SO close to the truth, apart from the hiccups you first mentioned. but this theory smooths all those hiccups out. AND the idea of the “thing she loved most” being a child is something ive been wondering for awhile. i really wouldnt be at all surprised if this is how it played out.
